ATTORNEYS United States Patent O llhll SEM-AUTMATC c'LlDEn MUNT FSRM'oses Perlman, dill@ ltd-th Ave., Brooklyn, NJ?. Filed Feb. 14, 196i,Ser. No. lidl 1 Claim. (Cl. 22h-2) The present invention relatesto'improvements in the art of assembling slide fastener parts so as tomake zippers or slide fasteners, and more specifica-lli the inventionrelates to Ia new and improved device for the mounting of the slidingand coupling members, which usually are called sliders on the rows oflinterdigitating elements of a slide fastener, so `as to complete slidefasteners or zipper units.

The attaching of sliders to zipper units, when done by hand requires acertain `amount of skill in order to complete any apprecaible quantityof zippers during a certain period of time; however, even skilledoperators are not able to `attach manually more than six thousandsliders to six thousand zipper units per day. The best mechanicaldevices hitherto developed have used a mechanism, actuated by solenoidsand micro switches. Such a mechanism is too expensive and toocomplicated for being used widely in the highly competitive business ofmaking slide fasteners.

Therefore, one object or" the present invention is the provision of adevice of the charac er described which simplifies and facilitates themounting of sliders on zippers to such an extent :that an unskilledworker can attach in a perfect marmer t* Telve thousand to thirteenthousand sliders to zippers during an ordinary eight-hour day.

Another object of the present invention is the provision of a device ofthe character described which is simple and inexpensive in constructionsince it consists of only a few parts that can be manufactured andassembled by mass production processes, and which does not require anyelectrical parts such as solenoids or micro switches or the like.

A further object of the present invention is the provision of a deviceof the character described which is comparatively small in size, andlight in weight, so that it can be installed easily or mounted on atable or ti e like -at locations which are most convenient in relationto other pieces of machinery used during the zipper making process.

With the foregoing and other objects which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts hereinafter more fully describedand pointed Out in the claim, it being understood that changes may bemade 4in the construction and arrangements of parts of the embodimentdisclosed without departing from the spirit of the invention as claimed.

In the accompanying drawing l have set forth an illustrative embodimentof my invention.

in said drawing:

FIGURE 1 is a top plan view of a preferred embodiment of my inventionwith a fraction of its top cover shown open so as `to present afractional top view of the inner mechanism;

FIG. 2 is a side elevation;

PHG. 3 is a detailed side elevation of the interior mechanical elementsof a modification; and,

FlG. 4 is ia fractional top view of the modified elements of FlG. 3.

Similar reference characters refer to similar parts throughout theseveral views.

In the drawing the numeral 1 denotes a casing having a top portion 2,and wall portions 3, as well as a llhfil base portion 4 (FIG. 2).Attached to a wall portion 3 f the casing l1 is a channel member :'swhich has a tf-shaped end portion 7 and a longitudinal channel l@ aswell as a traverse channel il. that crosses the channel it?, as may beseen in FIG. l. The member 5 also has a recessed portion l2 of asubstantially inverted U-shaped formation, and in which are rotatablyarranged a pair of disks l5, which have bevelled, reduced end portionsand are mounted on a shaft that is rotatably mounted in bearings 2l?.The bearings 2l) are mounted on the casing l, through a portion of whichthe shaft 17 is traverse-ly extended. A pair of ring `members 21 `and Z2are irmly secured to the `shaft i7, and a friction disk Z3 is secured to`the member 21. A sprocket wheel 2e is rotatably `and shiftably mountedon the shaft 17, and is connected by means of a sprocket chain Z5 to asmall sprocket pinion 27, that is secured to a shaft 30 of `a reductiongear 3l, which is in driving engagement with an electric motor 32mounted within the casing l.

A counter friction disk 33 or any other suitable surface preferably issecured to the wheel 24, and is in engagement with the friction disk 23,and `a pressure spring 34E- is interposed between the member Z2, and thewheel Zei', so that the member 2l and the shaft 17 will be taken alongand caused to rotate if the wheel 242- is being rotated, provided thereis no considerable force exerting a braking action on shaft 17, in whichcase a slipping of the elements 23 and 33 on each other will be caused,allowing a rotation of the wheel 2d without tacking along the parts 23,2l, 17 and l5.

One, or two, or more cross pins 35 are traversely extended from one or"the disks 15 to the other and are Secured thereto, A knob 37 is securedto that portion of the shaft i7 which `extends through the channelmember 5 and beyond the sane.

A slide arrester do, which may be of any suitable shape andconstruction, is mounted on the top wall portion 2 of .the casing l. inthe instance shown the arrester il@ consists of -a base l carrying abi-urcated upright member 4Z, to which is pivot-ally attached at 43, acurved lever A downwardly extendinfr oblique end portion d5 of the lever44 is forced by ya spring 49 to extend into the way `of a row of sliderse7, which are being slid down by means of gravity, from a sliderhandling device `(not shown), on a guide rail Si: toward theintersection of the channcls lll and .ll or" 'the inember i6.

lf the members l5 and d'7 `are rotating in a counterclockwise direction,any slider 47, extending into the channel l@ and arrested in its slidingmovement by the arrester dil, will be engaged by `one of the pins 35 andwill be moved away from the arrester 4i?, toward the end of the channeliti; there the thus engaged slider i7 will be stopped, and with it willalso be stopped any further rotation of the parts l5 and 17, while theelements Z3 `and 33 are in frictional relationship to one another. Thesaid stopped slider is now in a convenient position for being insertedby an operator in between the rows of interdigitating elements of aslide fastener or zipper unit. Thereby the said slider is removed fromthe device, so that the `aforerrientioned braking action ceases, andanother slider is bein-g pushed into the place of the aforementionedslider 57 by the action of the elements 35, l5 and l'l' in the abovedescribed manner.

According to the modification of FIGS. 3 and A., the elements l5, i7, iland 24 are replaced by a pair of wheels Sl mounted on a shaft 53, andconnected by a pair of chains Srl, or a belt or the iike,vto anotherpair of wheels S5, which are rotatable on a 4shaft 57. Here, the wheels5l are firmly secured tothe shaft S3, as are the disks lo' in theembodiment of FEGS. l and 2, and

the chains or the like 54 are connected to each other by traverse pinse@ which are adapted for eng-aging sliders in the same mmrner as thepins 3S of FlG'S. 1 and 2. Rotatably and shiftably to the strait 53 isattached la wheel 6l, which is driven by a belt 52 or the like, thatpasses round `a pulley 63 of a reduction gear 6d, driven by a motor 66.The wheel di also is provided with a friction surface 67, that is infrictioi a engagement with a friction disk 7i? attached to a ring member'7l which is rmly secured -to the shaft 53.

Since certain changes may be made in the above article and diierentembodiments ot the invention could be made without departing from thescope thereof, it is intended that all matter contained in the abovedescription or shown in the accompanying drawing shall be interpreted asillustrative and not in a limiting sense.

It is also to be understood Ithat the following claim is intended tocover all of the generic and specific features of the invention hereindescribed, and all statements of the scope of the invention which as amatter of language might be said to fall therebetween.
